Walking Through a Lesson What I notice, what I wonder, and what I'd do with it

NEW Post. I picked a random lesson and shared my planning: Walking Through a Lesson fawnnguyen.substack.com/p/walking-th...

I love the sites you’ve mentioned. I also love @fawnnguyen.substack.com’s site: www.visualpatterns.org, @kristenacosta.bsky.social’s site: kristenacosta.com/number-talk-..., and many others.

Thank you very much, Katrina.

Primary Numbers Turns out prime numbers are like red, blue, and yellow

Math Decoded Experience the joy of answering why in math class like never before Mathematics often feels like a collection of disconnected rules, but what if you c...

Just got Math Decoded by James Tanton and I'm so happy. 📚✨
It's pure James—accessible, joyful, with colorful sketches that are exactly what you need, right when you need them.
You can hear his voice on every page, kapows and all. So, so good.

When airlines use "minutes" to describe the delay.

That's what I'm saying!

:))

I can't afford first class, but I prefer the exit row for my long legs. And when the flight attendant asks, "Are you willing and able to perform emergency duties...," I respond with a firm yes.
This is a lie. My yes just means that I'm ready to die with the rest of y'all.

I mean is bay leaf the appendix of cooking? What does it do?

I've been making a lot of soups lately.

Has anyone done a blind taste test (like Pepsi vs Coke) to pick out the soup cooked with bay leaf vs. one without?

The one I linked to was the start of it - the spark to continue.

Find the Smallest Sum Building a thinking task that lets students discover patterns in arithmetic sequences

Happy Wednesday, everyone! I hope your winter break is just around the corner, and a good book 📚 or hot beverage ☕ is in your near future.

John!! I smile just seeing your name.
I definitely got this from the great Don Steward.

A4 Most recent re-learning was at NCTM and @fawnnguyen.substack.com session using Visual Patterns. I have been working with teachers and after my session of using Visual Patterns they all wanted www.visualpatterns.org and more on making connections. ❤️ Spreading the love of #Mathing.

When Students Write the Questions An alternative to endless practice: let students create the questions

Happy Friday!
Finally had time to write—latest post on having students create the questions: fawnnguyen.substack.com/p/when-stude...

It was an amazing experience. Your care, compassion, and sense of humor made the experience so memorable. Thank you!

Q1: I’d ask the student to explain their solution (the graph) in words. Hopefully, by saying it out loud, they’ll notice the numbering.
Q2: Can you test a couple of numbers in the region you shaded to see if they work?
Q3: I see that you have –3 as a solution. Please check that.
Etc.

Wonderful to meet you, Ryan. Thank you again for being there with me.

These are just warm ups- the key is SEEING the patterns visually

Really loved this episode! "Kids in math class can have different answers that are right and that they can be wrong in a smart way."

Don had such an amazing eye for a rich problem, that he always then turned into a rich, connected set of problems.
